Letters Patent No. 94,484, dated September 7, 1869?.

IMPROVEMENT IN WRENCHES FOR ELEVATING- PUMIP-TUBBS.

The Schedule referred to in thesa Letters Patent and making part of the same.

Be itkuowu that 1, Julius A. FLEMING, of Shamberg, in the county of Venango, and State of Penn- 1 sylvania, have invented a new and useful Improvement in Swivel-Wrench and Clamp for Artesian Wells; and I do hereby declare the following to be a a full, clear, and exact description thereof, reference being bad to the accompanying drawing, making a part ofthis specification, in which Figure 1 is a side elevation of my improvenient,

showing the manner of' slipping the wrench on to the rod.

I Figure 2 is a side elevation of the same attached to the rod.-

Figure 3 isan nd view of fig. 1, showing the wrenchhead and its. attachment to the shank.

Figure 4 is a side view of the jointing-end of a rod. Like letters of reference indicate like parts in each.

Hcrctofore, in putting in or removing the rods of oil and other deep wells, great difliculty has been experienced on account of the liability of the apparatus used, to let them slip and drop into the wells. This always involves a great loss of timcand money to the operators, for-they can only he recovered by grappling-irous and other instruments, and the use of these instruments in the contracted space of an oil-well is very tedious and vexatious.

- By my invention, not only do I rcmhi'e this serious" ditlicult-y, but am enabled to put in and take out ,the rods with great rapidity and case; and

The nature of it consists of a shank having a swivelhead and two arms, between which swings a wrenchhead, having a slotted aperture, the open end of which is closed by :1 lug, whichis brought opposite to it;

To enable others skilled in the artto make and use my invention, I will proceed to describe its construe tion and manner of use.

v a is the wrench-head. Y

Ir b are the arms of the shank c.

die the swivel-head.

e are lugs, attached to one of the arms I).

f .isthe slotted aperture in the wrench.

g is a rod, such as is used in oil-wells.

The shank a of the rod g, fig. 4, is made square, for convenience ,in removing it..

If it is desired to remove the rods from an oil-well, the wrench is laid horizontally along the surface,"so asto bring it at right angles'w'ith the end of the rod, which protrudes therefrom, and the slot f slipped on to the squared shank o.- (The rod when in this position is shown in red lines in fig. 1.) The shank He then drawn up by means ofa rope attached. to-the swivel-head (1, until it reaches a perpendicular. (The wrench in this position is shown in fig. 2.) This throws one of the lugs, e, into the open end of the slot 1; as

shown in'fig. 3, to secure the rod g effectually from all danger of slipping thelefi'oin. The wrench is thenhauled up by means of the rope attached to the swivelhead (1, until the end of the next section appears above the surface.

A second wrench, of similar construction, is attached to this'second section, in the manner herein- ,hcfore described. r 7 t The swivel-head thenbeing firmly held in position,

the shank is rotated iuiit, 'so as to unscrew the section of rod, held by the wrench-head a, from the section held below by the second wrench. It is then: let down by the rope, the shank-swuug around at right angles to the-section, so as to throwl the lug-efrom opposite the open end of the slot), and allow the section to be removed from the wrench-head.

The second section is then drawn up by the second wrench and removed in like manner; the first wrench in the mean time, having been attached to a third section. This operation is repeated until all the rods are removed.

If, for any reason, the rope should break, there is no danger of the tubing or rods dropping into the well beyond reach, ibr the wrench-heads being wider than the mouth of the well, catch tll0l80ll,ll-I1Il are stopped in their descent.

The'a-dvantages of my invention are its safety and the great saving in time and labor which :is accomplished byits use. I

Y The wrcueh may be made of malleable iron, or other suit-able material. 1 i

What I claim as my iuveutiomand desire to secure for the reception of a coupling-rod or tube, in combination with a lug, e, for' closing such aperture and holding the rod in place while being raised or unjointed, substantially as above set forth.

In testimony whereof, I, the said JAMES A. FLEM- me, have hereunto set my hand. I

, JAMES -A. FLEMING.
